In an electrochemical machining process using NaCl as electrolyte, the gap between the tool and workpiece is 0.30 mm and the supply voltage is 14 V DC. If the specific resistance is 4 Ω cm and cross-section machined is 30 mm × 30 mm, then which of the following are true? (Take A = 56, ρ = 7700 kg / m3, Z = 3)
1
Electrode feed rate = 0.00293 cm / s
2
MRR is 0.0263 cm3 / s
3
Current is 1050 A
4
None of these
